Cow's milk is one of the most allergenic foods in early childhood, being caseins and the two main whey proteins - ±-lactalbumin (±-La) and ²-lactoglobulin (²-Lg) - the major allergens. Enzymatic hydrolysis of proteins is generally used to produce hypoallergenic formulas, which are an alternative for infants with high risk or infants diagnosed with cow's milk allergy. However, in some cases, proteolysis does not totally eliminate allergenicity. Thus, alternative strategies have been studied aiming to reduce the residual antigenicity. The association of enzymatic hydrolysis with transglutaminase-induced polymerization has resulted on decreasing of antigenic response and can improve the functional properties of the proteins, such as solubility, emulsifying and foaming capacity, and gelling properties. Another strategy to protein allergenicity reduction that is recently getting attention is protein-polyphenol complexation. Nevertheless, studies of the effect of protein-polyphenol interaction on milk protein allergenicity are scarce and most of them are facing the impact of the complexation in bioactivity and bioavailability of phenolic compounds. In this sense, the aim of this study is to investigate two different treatments in order to obtain hypoallergenic products: enzymatic modification of whey protein isolate (WPI) in two stages (hydrolysis and polymerization) and complexation of WPI with phenolic compounds (caffeic acid and epigallo-catechin-gallate).
